Carrier and electric switch having said carrier

Abstract

A carrier for electrical and/or electronic components is provided, in particular, a printed circuit board, having a broadside for accommodating electrical conductor tracks, and having a narrow side. At least one electrically conductive contact area is provided on the carrier, the contact area, in particular, being used as a fixed contact for an electrical switch. The contact area is arranged on the narrow side.

The invention claimed is: 
     
       1. An electrical switch, the electrical switch comprising two fixed contacts on a printed circuit board and a switching contact for switching interaction with the fixed contacts, the switching contact is situated on a switching mat, which is arranged on a carrier part, and the switching contact interacts with the fixed contacts in a bridging manner, the printed circuit board having a broadside and a narrow side, wherein the fixed contacts are arranged in an extending direction on the narrow side and a notch is formed in the narrow side on one or another side of the fixed contacts so as to be at a spaced distance from the fixed contacts, with a latching hole formed in the broadside so as to be directly adjacent to the notch in a direction perpendicular to the extending direction of the fixed contacts, and wherein the carrier part having a stop and a latching hook is fastened to the printed circuit board such that the stop in the carrier part is pressed against the narrow side of the printed circuit board along the spaced distance between the notch and the fixed contacts and the latching hole in the broadside of the printed circuit board is fastened to the carrier part via the latching hook. 
     
     
       2. The electrical switch as claimed in  claim 1 , wherein the printed circuit board consists of electrically insulating material, and wherein the contact area consists of electrically conductive material. 
     
     
       3. The electrical switch as claimed in  claim 1 , wherein the contact area consists of a coating with an electrically conductive metal, and wherein the coating is partially formed on the narrow side. 
     
     
       4. The electrical switch as claimed in  claim 1 , wherein the switching contact comprises an electrically conductive pill, and the switching mat consists of elastomeric and/or elastic plastic. 
     
     
       5. The electrical switch as claimed in  claim 4 , wherein a recess is provided in the carrier part in such a manner that the contact area is exposed for making electrical contact with the switching contact. 
     
     
       6. The electrical switch as claimed in  claim 5 , wherein a fixing pin is provided on the carrier part for the purpose of arranging the printed circuit board in a housing. 
     
     
       7. The electrical switch as claimed in  claim 1 , wherein the printed circuit board is a carrier for electrical and/or electronic components. 
     
     
       8. The electrical switch as claimed in  claim 3 , wherein the coating is partial gold plating. 
     
     
       9. The electrical switch as claimed in  claim 4 , wherein the pill consists of carbon. 
     
     
       10. The electrical switch as claimed in  claim 4 , wherein the pill consists of graphite. 
     
     
       11. The electrical switch as claimed in  claim 4 , wherein the switching mat consists of silicone. 
     
     
       12. The electrical switch as claimed in  claim 1 , wherein the printed circuit board is provided as a carrier for electrical and/or electronic components, and wherein the broadside is for accommodating electrical conductor tracks.
